Description

Technical Field

[0001] This disclosure relates to the field of plate rolling equipment technology, and more specifically, to a plate rolling machine with a limiting device. Background Technology

[0002] Plate rolling machines, as core equipment in the field of metal sheet processing, are widely used in industries such as construction, chemical industry, machinery manufacturing, and shipbuilding. They are mainly used to roll flat metal sheets into cylindrical, conical, or other arc-shaped structural parts, and are key equipment for realizing the plastic deformation processing of sheet metal.

[0003] Traditional plate rolling machines require stopping the machine to disassemble the original fixtures and replace them with suitable fixtures when switching between processing narrow decorative thin plates and wide industrial thick plates. The whole process is time-consuming and labor-intensive, which not only reduces production efficiency but also increases the cost of equipment use. At the same time, problems such as plate offset and tilting are prone to occur during the adjustment of the fixtures, causing the limit wheels to not fit evenly against both sides of the plate. It is difficult to achieve stable clamping for plates of different thicknesses and materials. Therefore, a plate rolling machine with a limit device has been designed. Utility Model Content

[0004] To overcome the above-mentioned defects, the present disclosure provides a plate rolling machine with a limiting device, which solves the technical problem of unstable plate rolling in the prior art.

Two drive rollers are symmetrically rotatably connected between the main frame and the secondary frame. A clamping frame is fixedly connected to the front end of the operating table. A double-threaded rod is threadedly connected to the inner wall of the clamping frame. Two clamping plates are symmetrically slidably connected to the upper surface of the inner wall of the clamping frame. The inner walls of the two clamping plates are threadedly connected to the outer wall of the double-threaded rod. An adjusting box is fixedly connected to the top of the clamping plate. A worm gear is rotatably connected to the inner wall of the adjusting box. A worm is rotatably connected to the end of the adjusting box near the worm gear. The worm meshes with the worm gear. A connecting shaft is fixedly connected to the inner wall of the worm gear. One end of the connecting shaft extends out of the inner wall of the adjusting box, and a clamping frame is fixedly connected to the extended end of the connecting shaft.

[0006] For example, at least one embodiment of this disclosure provides a plate rolling machine with a limiting device, wherein one end of the drive roller extends out of the outer wall of the main frame, a driven gear is fixedly connected to the extended end of the drive roller, and a fixed frame is fixedly connected to the upper surface of the operating table.

[0007] For example, at least one embodiment of this disclosure provides a plate rolling machine with a limiting device, wherein a motor is fixedly connected to the top of the fixed frame, and a drive gear is fixedly connected to the output end of the motor, and the drive gear meshes with two driven gears.

[0008] For example, at least one embodiment of this disclosure provides a plate rolling machine with a limiting device, wherein the top end of the fixed frame is fixedly connected to an extension frame, the top end of the extension frame is threadedly connected to a limiting screw, and the bottom end of the limiting screw is fixedly connected to a limiting plate.

[0009] For example, at least one embodiment of this disclosure provides a plate rolling machine with a limiting device, wherein a lifting frame is slidably connected to the top of the main frame, a hinge frame is hinged to the top of the auxiliary frame, and a bearing block is sleeved on the inner wall of the hinge frame.

[0010] For example, at least one embodiment of this disclosure provides a plate rolling machine with a limiting device, wherein a plate rolling roller is rotatably connected between the lifting frame and the bearing block, a limiting pin is fixedly and slidably connected to the inner wall of the hinge frame, and an extension rod is fixedly connected to the top of the lifting frame.

[0011] For example, at least one embodiment of this disclosure provides a plate rolling machine with a limiting device, wherein two sliding blocks are symmetrically fixedly connected to the bottom end of the clamping plate, and the outer wall of the sliding blocks is slidably connected to the inner wall of the clamping frame.

[0012] For example, at least one embodiment of this disclosure provides a plate rolling machine with a limiting device, wherein one end of the double threaded rod extends out of the outer wall of the clamping frame, and a rotating disk is fixedly connected to the extended end of the double threaded rod.

[0013] For example, at least one embodiment of this disclosure provides a plate rolling machine with a limiting device, wherein two guide rods are fixedly and symmetrically connected to the top of the clamping frame, two sliding sleeves are fixedly and symmetrically connected to the inner wall of the clamping plate, and the outer wall of the guide rods is slidably connected to the inner wall of the clamping plate.

[0014] For example, at least one embodiment of this disclosure provides a plate rolling machine with a limiting device, wherein the top end of the worm extends out of the outer wall of the adjustment box, a knob is fixedly connected to the extended end of the adjustment box, and a limiting wheel is rotatably connected to the inner wall of the clamping frame.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: 1. Compared with traditional technology, this utility model has a clamping frame and clamping plate set at the front end of the operating table. By adjusting the double threaded rod by rotating the disc, the two clamping plates are pushed to slide to adjust the spacing. The spacing of the fiber limit is flexibly adjusted according to the different widths of the plate. During the sliding of the clamping plate, the sliding block at the top slides along the inner wall of the clamping frame, while the sliding sleeve guides along the outer wall of the guide rod. The double guide structure effectively avoids problems such as offset and shaking when the clamping plate slides, ensuring that the two clamping plates always remain parallel and move stably to both sides of the plate, so that the limit wheel can exert force evenly to clamp the plate.

[0016] 2. Compared with traditional technology, this utility model has an adjustment box and a clamping frame set on the top of the clamping plate. The operator can manually turn the knob to adjust the guide angle of the limit wheel by means of the meshing transmission of the worm gear and worm wheel. The stable clamping and limiting of the two limit wheels ensures that the plate moves along the preset trajectory during the conveying of the coil, effectively preventing the plate from deviating or twisting and ensuring the curvature of the coil.

[0025] like Figures 1-5The diagram illustrates a plate rolling machine with a limiting device according to an embodiment of this disclosure. It includes an operating table 1, a main frame 2 fixedly connected to the top of the operating table 1, a secondary frame 3 fixedly connected to the end of the operating table 1 away from the main frame 2, two drive rollers 4 symmetrically rotatably connected between the main frame 2 and the secondary frame 3, a clamping frame 16 fixedly connected to the front end of the operating table 1, a double-threaded rod 18 threadedly connected to the inner wall of the clamping frame 16, and two symmetrically slidingly connected rods 18 on the upper surface of the inner wall of the clamping frame 16. Clamping plates 17, the inner walls of the two clamping plates 17 are threaded to the outer wall of the double threaded rod 18, the top of the clamping plates 17 is fixedly connected to the adjusting box 21, the inner wall of the adjusting box 21 is rotatably connected to the worm wheel 22, the end of the adjusting box 21 near the worm wheel 22 is rotatably connected to the worm 23, the worm 23 meshes with the worm wheel 22, the inner wall of the worm wheel 22 is fixedly connected to the connecting shaft 26, one end of the connecting shaft 26 extends out of the inner wall of the adjusting box 21, the extended end of the connecting shaft 26 is fixedly connected to the clamping frame 25.

[0026] like Figures 1-5 As shown, a plate rolling machine with a limiting device is shown in one embodiment of the present disclosure. One end of the drive roller 4 extends out of the outer wall of the main frame 2. The extended end of the drive roller 4 is fixedly connected to a driven gear 5. A fixing frame 6 is fixedly connected to the upper surface of the operating table 1.

[0027] A motor 7 is fixedly connected to the top of the fixed frame 6, and a drive gear 8 is fixedly connected to the output end of the motor 7. The drive gear 8 meshes with two driven gears 5.

[0028] It should be noted that motor 7 is based on servo motor model SGM7G-09AFC6. After motor 7 starts, it drives drive gear 8 to rotate. The rotation of drive gear 8, through meshing, drives two drive rollers 4 to rotate in different directions, thereby driving the plate to perform the rolling operation.

[0029] like Figures 1-5 As shown, a plate rolling machine with a limiting device is illustrated in one embodiment of the present disclosure. An extension frame 14 is fixedly connected to the top of the fixed frame 6. A limiting screw 15 is threadedly connected to the top of the extension frame 14. A limiting plate 1501 is fixedly connected to the bottom of the limiting screw 15.

[0030] It should be noted that a manual wheel is provided at the top of the limiting screw 15. By rotating the manual wheel, the limiting screw 15 can be rotated. The limiting screw 15 slides on the inner wall of the extension frame 14 by rotating. The limiting screw 15 pushes the limiting plate 1501 to press and limit one end of the lifting frame 9.

[0031] like Figures 1-5As shown, it illustrates a plate rolling machine with a limiting device in one embodiment of the present disclosure. The top of the main frame 2 is slidably connected to a lifting frame 9, and the top of the auxiliary frame 3 is hinged to a hinge frame 10. The inner wall of the hinge frame 10 is sleeved with a bearing block 12.

[0032] A rolling roller 11 is rotatably connected between the lifting frame 9 and the bearing block 12. A limiting pin 13 is fixedly and slidably connected to the inner wall of the hinge frame 10. An extension rod 901 is fixedly connected to the top of the lifting frame 9.

[0033] It should be noted that the bottom of the lifting frame 9 is equipped with a driving lifting device. By starting the lifting, one end of the lifting frame 9 and the rolling roller 11 can be raised. The operator can manually pull out the limiting pin 13. After the limiting pin 13 is pulled out, the lifting frame 9 pushes one end of the rolling roller 11 to rise and fall. At this time, one end of the extension rod 901 is restricted by the limiting plate 1501. The connection between the rolling roller 11 and the bearing block 12 on the other side will be tilted upward on the inner wall of the limiting pin 13. At this time, the rolling roller 11 and the bearing block 12 are in a weightless state. The bearing block 12 can be removed and the limiting pin 13 can be flipped. The rolled plate can then be taken out through one side of the rolling roller 11.

[0034] like Figures 1-5 As shown, it illustrates a plate rolling machine with a limiting device in one embodiment of the present disclosure. Two sliding blocks 1701 are symmetrically fixedly connected to the bottom end of the clamping plate 17, and the outer wall of the sliding block 1701 is slidably connected to the inner wall of the clamping frame 16.

[0035] It should be noted that the inner wall of the clamping frame 16 is provided with a sliding groove, and the clamping plate 17 can slide along the inner wall of the clamping frame 16 with the help of the sliding block 1701.

[0036] like Figures 1-5 As shown, a plate rolling machine with a limiting device is illustrated in one embodiment of the present disclosure. One end of the double threaded rod 18 extends out of the outer wall of the clamping frame 16, and a rotating disk 19 is fixedly connected to the extended end of the double threaded rod 18.

[0037] It should be noted that the operator can rotate the double threaded rod 18 by rotating the rotating disk 19. The surface of the double threaded rod 18 is provided with two threads with opposite directions. One end is threaded to a clamping plate 17. When the double threaded rod 18 drives the two threads to rotate, the two clamping plates 17 will be pushed to slide to the opposite side through the threaded connection, thereby adjusting the distance between the two clamping plates 17.

[0038] like Figures 1-5As shown, a plate rolling machine with a limiting device is illustrated in one embodiment of the present disclosure. Two guide rods 20 are fixedly and symmetrically connected to the top of the clamping frame 16, and two sliding sleeves 1702 are fixedly and symmetrically connected to the inner wall of the clamping plate 17. The outer wall of the guide rods 20 is slidably connected to the inner wall of the clamping plate 17.

[0039] It should be noted that when the operator rotates the double threaded rod 18 to push the two clamping plates 17 to slide, the clamping plates 17 can slide along the outer wall of the guide rod 20 with the help of the sliding sleeve 1702, thereby stabilizing the sliding of the clamping plates 17.

[0040] like Figures 1-5 As shown, a plate rolling machine with a limiting device is illustrated in one embodiment of the present disclosure. The top end of the worm gear 23 extends out of the outer wall of the adjustment box 21. A knob 24 is fixedly connected to the extended end of the adjustment box 21. A limiting wheel 27 is rotatably connected to the inner wall of the clamping frame 25.

[0041] It should be noted that the operator can rotate the worm gear 23 by turning the knob 24. The rotation of the worm gear 23 will drive the worm wheel 22 to rotate. The rotation of the worm wheel 22 will adjust the angle of the clamping frame 25, and the limit wheel 27 will limit and guide the plate.

[0042] Working principle and usage process of this utility model: The specific operation is as follows: First, the operator needs to adjust the distance between the two clamping plates 17 by rotating the rotating disk 19 according to the width of the board. The rotating disk 19 will drive the double threaded rod 18 to rotate. When the double threaded rod 18 rotates, it will push the two clamping plates 17 to slide to both sides of the board through the threaded connection. The top of the clamping plate 17 will slide along the inner wall of the clamping frame 16 with the help of the sliding block 1701. At the same time, it can also be guided along the outer wall of the guide rod 20 through the sliding sleeve 1702. With the assistance of the sliding block 1701 and the sliding sleeve 1702, the clamping plate 17 will drive the limiting wheel 27 to clamp the two sides of the outer wall of the board. After completion, the operator can also manually rotate the knob 24 to adjust the guide angle of the two limiting wheels 27. After the knob 24 is rotated, it drives the worm gear 23 to rotate. The worm gear 23 will drive the worm wheel 22 and the connecting shaft 26 to rotate through meshing. The connecting shaft 26 will further drive the clamping frame 25 and the limiting wheel 27 to rotate. The operator rotates the clamping frame 25 and the limiting wheel 27 to adjust the guiding angle of the plate. After adjustment, the operator needs to start the motor 7. The motor 7 will drive the drive gear 8 to rotate through the output end. The drive gear 8 will drive the two driven gears 5 to rotate through meshing. The driven gears 5 will further drive the two drive rollers 4 to rotate. At this time, the operator needs to transport the plate between the rolling roller 11 and the drive roller 4 under the clamping and guidance of the two limiting wheels 27. The plate is rolled and transported under the rotation of the rolling roller 11 and the drive roller 4. At the same time, the conveying end of the plate will be horizontally and stably rolled under the limit of the limiting wheel 27. After the plate is rolled, the operator needs to pull out the limiting pin 13 and drive the lifting frame 9 to rise. At this time, the extension rod 901 at one end of the lifting frame 9 will be resisted by the limiting plate 1501. The bearing block 12 at the other end of the rolling roller 11 will be tilted due to the limitation of the extension rod 901. When the rolling roller 11 After one end of the bearing block 12 is lifted, the operator can pull out the bearing block 12 and flip it over through the hinge. After flipping, the operator can slide the rolled plate out through one end of the rolling roller 11.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
